Warehouse temperature and humidity monitoring
Plan an RS485 network with AW3485A transmitters, a gateway and a monitoring host.
Engineering reference, not a completed customer case study.
Validation
- Place sensors at representative storage locations, away from doors, direct sunlight and local heat sources. Determine the point count through site mapping, not floor area alone.
- AW3485A publishes RS485 Modbus RTU, a 2.5 s sampling interval, 9-36 V DC or USB 5 V supply, and accuracy of ±0.3 °C / ±2% RH. Check wiring and the ordered variant before installation.
- Use unique device addresses and validate bus polarity, grounding, termination and gateway settings. The base AW3485A does not include the relay outputs of the AW3485A-KC variant.
- Commission by comparing readings with a traceable reference, simulating communication loss and checking alarm delivery and record timestamps. Retention and alert rules are project requirements, not guaranteed product functions.
